Lying in bed before going to bed at night, slide your hands from your chest to your navel for 30 times, then slide them from your ribs to your navel for 30 times. Hold your hands in an empty fist shape and pat them on your waist (not too hard) until the meat on your stomach feels a little shaky. Do it every night before going to bed, and there will be exhaust after a few days, which will have the effect of losing weight.
